A citizen of the United States, and a resident of The dynamo is placed on a cage, which is the borough of Brooklyn, in the city'and State suspended by its inboard side from the end 5 of New York, have invented certain new and of the truck outside of or beyond the same.

useful Improvements in Means fo'r' Connect- The manner and means by which this is done ing Dynamos with the Trucks of Railwayare as follows: 4 4 are bars, preferably of Cars; and I do hereby declare that the folwrought-iron andeachintegral throughoutits lowing is a full, clear, and exact description lengthand conformation. These are placed 10 of the same, reference being had to the acparallel, or practically so, with each other.

Then it Figure 1 is avertical longitudinal sectional extends outward over the outboard beam B, View of an apparatus made according to my thence farther outward beyond the end of I 5 invention.

One

At the back or inboard side of the Q in motion. suspended portion of each bar is a brace M,

The object of my invention is to provide one end of which is riveted or bolted, as at 25 mechanism for such purpose which shall be c, to the said portion of the bar, while the strong, simple, and durable and not liable opposite or inboard end is in like manner to get out of order under the rough usage to :m'ade fast, as at b, to the inboard end of the which apparatuses for such purposes are necsaid bar. The effect of these braces is to essarily subjected. To this end my said instiffen the suspended portions of the bars C C 30 vention comprises certain novel combinations against thrust in an inward direction. To furof parts hereinafter fullyset forth and shown. ther strengthen this operation of the braces,

A and B are cross-beams which form parts each has at the upper side of its inboard end of the frame of a railway-truck, which latter a shoulder f, which rests against the lower may be ofanysuitable construction. As such part of the beam A,-and at its under side a 35 trucks are well known in the art, it'is thought shoulder g, against which abuts the end of the that further description or illustration of the contiguous brace M, said end being bolted, as truck is here unnecessary. In the drawings, just mentioned, to-the bar C.

For con- At the bottom of the cage are provided bear- Venience I designate this pulley as the dyings m for a shaft n,which extends across namo-pulley.- Ordinarily this dynamo-pulfrom one of the bearings m to the other. The ley is of smaller diameter than the pulley E dynamo is so connected with this shaft n that on the axle. From the pulley E to the dyit is capable of a rocking movement, which maybe secured either by permitting the shaft m to move in the bearings 07. or by permitting the dynamo to turn in opposite directions upon the shaft. At the top of the dynamo (as here used the term dynamo includes the frame or inclosing shell of the dynamo proper) are lugs r, to each of which is pivoted the outboard end of a slide N, the opposite end portion of which works in a guide .9, fixed above or adjacent to the dynamo. This guide may be provided by a vertical plate 25, bolted to the outboard beam B and having a hole or opening through which the inboard portion of the slide is passed. The slide has a strap it, between which and the guide 3 is a spring 10, which presses in an outward direction that is to say, against the strain exerted upon the dynamo by the tension of the belt K.

In the operation of the apparatus the motion transmitted from the axle D to the dynamo-shaft I actuates the dynamo,from which the current may be transmitted by any usual or suitable means. The driving-belt K is kept at a substantially uniform tension at all times. The dynamo being held between the tension of the belt and the elastic pressure of the spring is less subject to the detrimental effects of jar and concussion than is possible with a more rigid support. The mechanism is extremely strong and durable and with practically a minimum of essential parts, so

- that a high degree of permanence, stability,

and d urability is secured notwithstanding the more or less rough usage to which apparatuses for such purposes are necessarily subjected under the severe conditions of actual use.

lVhat I claim as my invention isl. The combination with arailroad-truck, a driving-pulley fast on an axle of the truck, a dynamo carried by the truck, and a drivingbelt from the pulley on the axle to the dynamo-pulley, of a support for the dynamo outside of the truck composed of bars fast at their inward ends to an inward cross-beam of the truck, extended outward over an outboard beam of the truck and beyond the latter and thence shaped to form a cage for the dynamo, then inward and back to the truck, means for attaching the said bars to the truck, and means for releasing the dynamo in the cage, as described.

The combination with a railroad-truck, a driving-pulley fast on an axle of the truck, a dynamo carried by the truck, and a drivingbeit from the pulley on the axle to the dynamo-pulley, of a support for the dynamo outside of the truck composed of bars fast at their inward ends to an inboard cross-beam of the truck, extended outward over an outboard beam of the truck and beyond the latter, then shaped to form a cage for the dynamo and thence inward and back to the truck, means for securing said bars to the truck, braces extended from the inward side of the cage to the inboard ends of the bars, and means for securing the respective ends of said braces to the adjacent portions of the bars,as described.

3. The combination with a railroad-truck, a driving-pulley fast on an axle of the truck, a dynamo carried by the truck and a belt from the pulley on the axle to the dynamo-pulley, and a support for the dynamo composed of bars extended from an inboard cross-beam of the truck outward over an outboard crossbeam of the same to and beyond the end of the truck, then bent to a shape requisite to form a cage for the dynamo, and thence inward back tothe truck, of a pivotal support for the dynamo at the bottom of the cage, and means for elastically pressing the dynamo in a direction against the strain exerted by the tension of the belt, as described.

4. The combination with a railroad-truck, a driving-pulley fast on an axle of the truck, a dynamo carried by the truck, and a belt from the pulley on the axle to the dynamo-pulley,
